RRH is dead. How can it be that the service still shows the person as RHH?
Amongst other sources, the RHH service uses the shareholder register to calculate RHHs. This register is only updated yearly, and although the relevant person is removed from the business register, the name may still appear as a RHH.
If you have access to the national population register you will receive a notification of the persons death in addition to the death date. This assumes that a 1:1 search is used.
